Mining operations and the desert landscapes of Pima County define this survey, which captures a region in transition as industrial sites sit alongside the Ironwood Forest National Monument. To the southwest, the Silver Bell (Site) is surrounded by evidence of intensive excavation, including a large Tailings Pond, numerous Mine Shafts, and an Adit near Portland Ridge. This proximity of heavy industry to protected lands creates a stark contrast between the modified terrain of the copper mines and the undisturbed peaks of the Silver Bell Mountains.
